A Chinese Puzzle

NANHAI, China &ndash; The third of August was a red-letter day for workers at Guangdong Chigo Air Conditioning. Minutes after the close of the workday, dozens stood eagerly in line for a rare treat in this dusty industrial town: free run of the shady, company-owned orchard, filled with ripe pomegranates. "This is a very nice benefit," said one of the workers, 21-year-old Chen Ya-xi, who rushed in after flashing her company ID to guards at the gate.
